A/N: It's time for the first real lemon of this story!

Despite Lenalee's assurances, Allen was still terrified of letting Kanda touch him. But between her pestering and Kanda's near constant attempts to instigate sex, he was reaching the end of his rope. So, for the sake of his sanity, he decided that it was time to just do it and get it over with. He had spent much more time worrying about sex than the actual act would take, so even though his heart wasn't necessarily in it, he was going to go through with it. Maybe if Kanda finally fucked him, the samurai would leave him alone for a while.

Allen had no clue how to actually tell Kanda that he was ready for sex, at least, not without admitting that he was only doing it to get it over with - something that was sure to upset the samurai and cause yet another long drawn out discussion. So he had to come up with a different way to go about it, and he was at a complete loss for what that might be.

But as he climbed in bed with his husband that night, he suddenly knew exactly what to do. Kanda always kissed him goodnight, so it shouldn't be too difficult to deepen that kiss and instigate things that way. Except life had other plans.

Kanda could tell that something was on Allen's mind; the boy was much more distracted than he usually was. And given that Lenalee had laid into him earlier that morning for not telling her that he'd married Allen, it wasn't hard to guess what was bothering the Moyashi. So he decided to give him the night off. He was not going to try to convince Allen to sleep with him that night. Once they were both settled under the covers, he turned out the lamp and rolled over without saying anything to the Moyashi first.

Allen could only blink at the samurai's back in confusion. He didn't understand why Kanda had suddenly broken that tradition or why the lack of a goodnight kiss had made him feel so lonely. "You're not going to kiss me?"

The question caught Kanda by surprise. His chest hurt from the rush of hope that welled up inside him at the thought that Allen actually liked their bedtime routine and might finally be warming up to him. He rolled back over and tried to study the Moyashi's expression. "Do you want me to?"

"Yes." Allen wasn't sure what he actually wanted and had only said that so he could proceed with his plan, but when Kanda's lips met his and that lonely feeling disappeared, he didn't regret that choice.

This time it was Kanda's turn to be caught by surprise. He pressed the usual chaste kiss to Allen's lips, expecting the Moyashi to be as unresponsive as always, but instead, those beautiful coral lips moved. Allen was kissing him back. He knew he might regret his next move, as it would probably scare the boy off, but he was so happy that he just couldn't help himself - he'd been waiting for over a month to get that reaction out of the Moyashi. He slid a hand into Allen's white hair, tangling his fingers into the soft strands, and then he pressed his tongue into the boy's mouth. He focused on savoring what was sure to be a brief taste, but it was time for another surprise. Allen wasn't pushing him away, he was pulling him in. The boy's arms were around his waist, guiding their bodies closer together as his mouth grew less hesitant in echoing Kanda's movements.

Kanda was both thrilled and terrified by the Moyashi's actions. It was entirely possible that the little trickster was up to something, but at the same time, he wanted this to happen so badly that he didn't think he cared that the Moyashi might be messing with him.

When they finally broke apart for air, Allen was panting heavily, but he made no move to end the making out, so Kanda reclaimed his lips, attacking him with more ferocity, encouraged by the fact that the Moyashi wasn't resisting. And the longer they kissed, the more he convinced himself that Allen truly wanted to have sex with him. After all, the bulge pressing against his thigh was definitely getting harder.

Allen was scared of the fact that he was enjoying what was happening. His plan had been to simply go along with whatever Kanda wanted to do to him, but he hadn't anticipated liking any of those things. It terrified him to think that he got pleasure from being touched by Kanda, mostly because that would mean that Lenalee and Kanda were right about him being attracted to the samurai, and he still very stubbornly refused to admit to that fact. But the way Kanda's hand was caressing his head and the way those slightly chapped lips attacked his with an almost bruising force gave him an undeniable sense of pleasure.

Stressed out by his inner turmoil, Allen snapped when Kanda suddenly made a move for his waistband. He forgot all about the fact that he had decided to see this through to the end and gave in to his doubts and self-consciousness. He jerked away from the kiss and shoved Kanda's hands away.

The reaction confused Kanda. "I thought you wanted this, Moyashi."

In his panic, Allen found the truth spilling out. "Not if this is all just a ploy so that you can see me naked again and make fun of me."

Kanda wanted to know where the Moyashi got the idea that he wanted to tease him, but he was much more concerned by the self-loathing that was hidden in the comment. "Why would I make fun of you for being naked?"

The answer to that question was hard to say out loud, but it was easier to say it than to let Kanda discover it by seeing it. "Because I'm ... inadequate."

It didn't take Kanda long at all to figure out what the Moyashi was referring to, and it shocked him that Allen was being so self-conscious because he thought his penis was small. After all, he had seen the boy naked before and found him to be just the right size. "You're not inadequate. You're perfect."

Allen scoffed at that. "You don't really mean that. You'd say anything to get sex from me."

The accusation earned him a flicked ear. "We've been married for four weeks. If I was any good at convincing you to have sex, we'd have slept together already."

Allen snickered at the comment, and Kanda quickly took advantage of his distraction and pulled his pants off his hips. The revealed cock looked exactly the same as it did in his memories, making him even more confused as to why the Moyashi thought he was small.

The moment Allen realized that his length was exposed, he covered himself with his hands, causing Kanda to groan in annoyance. "Come on, Moyashi. It's been in my mouth. Do you really think I have a problem with it?"

Allen faltered under that logic. "I guess not, but it's still... you know..."

Kanda rolled his eyes at that. "You're only seventeen, you-"

"I'm twenty."

At the correction, Kanda rolled his eyes once more. "Not for two more months. And that's not what I was talking about. Your body is seventeen, so you have a seventeen-year-old's penis. And I happen to think that it suits you. It's the perfect size for your frame. It may not be anything impressive compared to whoever it is that you're comparing it to, but considering that you're five-ten and a hundred pounds soaking wet, it's actually a pretty decent size."

Allen turned beet red and hissed in embarrassment. "Don't say things like that!"

Seeing that he was getting nowhere, Kanda decided to try a new tactic. If there was anyone out there who could understand what the Moyashi was going through, it was Kanda himself, and it was time to remind him just how much they had in common. "Look. Your body's stuck at seventeen. So what? Mine's stuck at nineteen. I'm not any more developed than you are."

Kanda was expecting Allen to blush and argue with him, but what he got instead was a resigned sigh. "Right. I forgot that you were immortal like me." After a pause, he tacked on, "That certainly gives a whole new meaning to 'till death do us part'."

Not knowing what else to do, Kanda just rolled his eyes at the comment. "I don't know how many times I've told you this, but I guess I have to say it again. We're not immortal, Moyashi."

Like always, Allen just shrugged off the reminder. "Komui says we are."

"No, Komui says we might be. We're going to have to live a hell of a lot longer before we know anything for certain. Now stop trying to change the subject." After giving Allen a very pointed look, Kanda continued with his original subject. "The point was that I'm stuck as a teenager too. I may not understand why you're so self-conscious about that fact, but I do understand what it's like. Doesn't that earn me at least a little trust?"

When Allen didn't respond right away, Kanda decided that he had had enough. He was tired of having his chances for sex thwarted by the Moyashi being overly emotional. There was no point in dragging this conversation on any longer if it was just going to go the same way as their previous discussions. "Do you want to have sex or not, Moyashi?"

"...Yes." It wasn't entirely true, but Allen was still determined to do it and get it over with.

"Then shut up and stop fighting me." Following the command, Kanda captured Allen's lips once again.

Allen resisted the kiss at first, but once he understood Kanda's unspoken point, he gave in. Their conversation had gone on for far too long, and it was time to either have sex or go to sleep. And Allen could almost kick himself for that; he had decided to go through with this because he was tired of talking about it, but when the moment came, he had only delayed it with more talking. So he decided to stop thinking and give in.

The moment Kanda felt Allen's lips start to move with the kiss, he rolled them over so that the Moyashi was on his back and he was kneeling over the boy. He focused all of his attention on the kiss, plundering the boy's mouth with his tongue and reveling in his unique taste. Kanda wasn't a fan of sweet things, but he could definitely make an exception for Allen. He didn't think he'd ever get tired of making out with the Moyashi.

As much as he enjoyed kissing, Kanda was ready for more. However, he knew that Allen wasn't there yet, so he continued with his assault on the Moyashi's mouth, waiting for Allen to relax and give in a little bit more. He knew the time was right when Allen's fingers began scrabbling against his head. The Moyashi was clearly trying to reach his hair tie, forgetting that the samurai had already gotten ready for bed and the ponytail was tied at the base of his skull rather than high like he wore it during the day. It was amusing, but it meant that Allen was ready for more.

Breaking the kiss, Kanda trailed his tongue over to the base of Allen's jaw, using the way the boy quivered as a gauge to find a sensitive spot. And once he found that spot, he nipped and sucked at it unrelentingly, loving the way the Moyashi whimpered and moaned in pleasure. The boy had been relatively silent thus far, but under the force of the hickey, he became quite vocal. The cries were embarrassing, but he couldn't hold them back; what Kanda was doing to him felt too good.

Kanda finally let go once the spot was bright red, hoping that the mark would last for a few days. He turned his attention lower, but the Moyashi's torso was still covered by his shirt, so he went even lower, pleased that Allen's length was no longer flaccid. He briefly debated teasing the Moyashi by playing with his shaft, but after what happened earlier, it was best to save that for another time. Gripping the hem of Allen's shirt, Kanda yanked it upward, intentionally getting him tangled in it to distract him. While Allen worked his way out of his shirt, Kanda attacked his chest, scraping his teeth against one of his pert nipples and making Allen scream.

Escaping from his sleep shirt was hard when Kanda was sucking on his nipple and making his whole body writhe in pleasure, but Allen managed to do it. He had somehow even managed to kick his pants the rest of the way off in the process, though that was probably from all the squirming he was doing. Now completely naked, he almost gave in to those same self-conscious feelings that had halted things earlier, but he pushed them aside in favor of powering through; it certainly helped that Kanda hadn't faltered in his ministrations and Allen's thoughts were hazy with pleasure.

Unsure of what to do next, and not wanting to just lay there and let Kanda be completely in control, Allen reached out for Kanda's shirt, barely succeeding at taking hold of the fabric. He tried to tug the garment upward, but failed miserably when Kanda gave his nipple a particularly strong suck. But to his surprise, Kanda responded to the feeble tug, releasing Allen's chest and sitting up to pull off his shirt.

The moment Kanda slipped off his shirt, any reluctance for sex that Allen might have had left vanished completely. With all of his worrying about intimacy and feelings, Allen had forgotten just how perfect Kanda's body was. And seeing that bare chest now, with its perfectly toned muscles and flawless skin, he could only think about seeing the rest of his husband's body naked. Of course, once he admitted to himself that he not only found Kanda attractive, but had thought of the samurai like that for quite a while, Allen found himself wondering why he had put off the sex for so long.

There was no time to think about that at the moment however. Once Kanda's shirt was tossed aside, he was kneeling back over the Moyashi, leaving another hickey on the boy's neck. Allen moaned, and now that he was much more interested in what they were doing, he began to buck his hips with purpose, rather than just letting his body do whatever it felt like. He pressed his groin feverishly against Kanda's, desperately trying to increase the friction between them.

Allen whined at the feeling of loss that filled him when Kanda pulled away and climbed off the bed, but as he watched the samurai remove his pants, he knew that the distance was worth it. Kanda's lower body was just as perfect as his torso was. Kanda rooted through the bedside table and gave the fingers of his right hand a liberal coating of lubricant before he returned to the bed, very aware of the fact that the Moyashi was watching his every move and drooling as he did so.

Kneeling between Allen's legs, Kanda used his dry hand to hook one of those long slender limbs over his shoulder. Finding the Moyashi's hole, Kanda slipped one of his lubricated fingers inside. Allen grunted and narrowed his eyes in confusion at the intrusion, not understanding what was going on, but he kept his questions to himself. However, when all Kanda did next was shove another finger inside him, Allen couldn't keep quiet any longer. "What do you think you're doing with your fingers?"

"Stretching you." Kanda's sarcasm faded when he actually processed the confusion on the Moyashi's face. His tone may have been offended, but the question was genuine. Allen really didn't know that his hole needed to be stretched. "If I stretch you with my fingers, it'll loosen up the muscles so that it won't hurt when I take you. You'll probably be a little sore in the morning, but you won't bleed or end up unable to walk like last time."

"Oh."

Allen blushed in embarrassment, but when he closed his eyes to fight back the tears, he found Kanda's lips on his. He reopened his eyes to find a gentle expression on the samurai's face. "There's nothing to be embarrassed about, Moyashi. You didn't know. Just forget about it and move on."

Kanda pressed another kiss to Allen's lips, this one fierce and passionate rather than chaste in order to build the heat back up between them. When the Moyashi relaxed and began to return the kiss, Kanda resumed moving his fingers, scissoring and stretching the passage as he searched for that one spot that he knew would make Allen fully give in. He knew he found it when the Moyashi suddenly froze before he practically convulsed with pleasure.

Though he was tempted to continue to tease the spot until the Moyashi came undone, Kanda knew that it was more important to make sure that he was properly stretched. If he ever wanted to have sex with Allen again after this, he needed to make sure that this time was as different from the last as possible; if the Moyashi ended up hurt in any way, he was not going to let Kanda touch him ever again.

So Kanda focused on getting the Moyashi as loose as possible, only occasionally brushing against that spot whenever Allen got too tense. And once Allen's hole was ready, Kanda pulled out his fingers and adjusted his position between the boy's legs. He pushed his length as gently into the waiting hole as he could, which didn't seem gentle at all, with how long he'd ignored his own need.

Allen grunted at the intrusion of Kanda's cock into his passage, but he managed to hold back the urge to fight against it, knowing that that would only make it hurt more. When Kanda was fully sheathed inside him, Allen expected the samurai to start moving right away, but instead, Kanda held completely still. He was giving the Moyashi time to relax and get used to his size, but Allen didn't know that and just stared at him in confusion, wondering why things had suddenly stopped.

The blank look on Allen's face was adorable, and that was a dangerous thing when Kanda was working so hard to hold himself back. So when the moment had stretched on for too long, he had to give the boy some prompting. "Just tell me when you're ready, Moyashi."

"I'm ready."

The hint of tears in the Moyashi's silver eyes contradicted the words. "Are you sure? I don't want to hurt you."

"Oh." Suddenly understanding, Allen smiled and blinked away his tears. "Yeah, I'm sure. It's just uncomfortable. It doesn't hurt anymore."

That smile was beautiful and genuine, so even though he didn't really believe the words, Kanda gave in. He slid his length almost all the way out of the Moyashi before thrusting it back in. The action was rewarded with a grunt and a look of complete and utter surprise, and the way Allen's jaw had gone slack told him that the boy hadn't expected that to feel good. After a few more experimental thrusts, Kanda began to pick up speed, enjoying the friction of the Moyashi's tight hot walls against his shaft. He was no longer worried about hurting the boy, not when Allen was crying out with pleasure with each thrust and literally begging for more, which meant that he could finally focus on his own needs.

And once Allen figured out that he didn't have to just lay there and take it, that moving his body increased not only his own pleasure but Kanda's as well, he began bucking his hips to match the rhythm the samurai had set. Sweat-slicked bodies moved in unison, building up the heat and tension between them. All was silent save for the sounds of bedsprings squeaking and heavy breathing that filled the air.

But then one of Kanda's thrusts hit Allen's prostate and it was all over. Having that sensitive spot rammed dead on filled Allen's already overheated body with so much pleasure that he immediately came undone, screaming and releasing his load all over his stomach. The Moyashi came without warning, and the delicious way he cried out combined with the unexpected spasming of his passage pushed Kanda to the edge. He found himself releasing inside Allen much sooner than he would have liked, but the pleasure he felt silenced his pride, allowing him to enjoy the fact that he had finally had consensual sex with his Moyashi.
